Research Of Ammunition Fuse Packaging Sealing Machine Sealing

For metal cans of ammunition fuse product packaging, and its extremely strict security requirements, should be resolutely put an end card cans, dumped cans, cans and pour ineffective sealing products such phenomenon. However,BFJ2-4-automatic sealing machine for metal cans on fuse occasionally occur card packaging cans and poor quality curling phenomenon was Found. If the seal is bad, because of the product stored a long time, it will inevitably result in the fuse quality problems and use fail, for example, when detonated blind fire, explosion, or as early as late burst and other dangerous problems, so it is necessary to carry out seaming process safety research and analysis.The research subjects were BFJ2-4-type sealing machine sealing bead metal round cans during two processes and two wheel roller grooves curve studies. Through the two re-sealing machine hemming process and a detailed analysis of transmission system, thereby affecting seaming summed up a common safety factors, theoretical analysis calculated movement and location parameters. At the same time create an entity model, using the finite element software ANSYS LS-DYNA explicit dynamic development of the model analysis and simulation, further, two wheels were optimized trench curve and get the best two wheel seaming curves and ensure the quality and packaging of ammunition fuse safety.This paper also discussed common problems and rollers on the common seal wear, causes and extend tire life. Based on the head and said crimping rollers conditions of each parameter the analysis of two double seamed sealing process analysis. Meanwhile brief description of the finite element ideas and ANSYS LS-DYNA basic theory and methods, the use of the software on two crimping forming process simulation, completely solve the ammunition fuses achieve automatic packaging sealing machine at the time of sealing bead metal cans various insecurity.
